HtmlViewGo()

Please, someone know IF can I resolve the following problem? [I've looked via the search function - but it seems that none had the 'problem'...]

Import MaxGui.Drivers
Strict 
Local window:TGadget
Local htmlview:TGadget
window=CreateWindow("My Window",30,20,600,440,,15|WINDOW_ACCEPTFILES)
htmlview=CreateHTMLView(0,0,ClientWidth(window),ClientHeight(window),window)
SetGadgetLayout htmlview,1,1,1,1 
Local bmaxdir$ = Getenv_("BMXPATH") 
Local result:Int = HtmlViewGo(htmlview , bmaxdir + "\docs\html\index.html") 'the file Index.html exists...
Print "Exists: "+result
While WaitEvent()
	Select EventID()
		Case EVENT_WINDOWCLOSE
			End
	End Select
Wend

If the URL exists then the HTML gadget opens and shows the .html page.
If you wrote/change the name (ie: index2.html and the file DO NOT EXIST) - the system-InternetExplorer shows an alert ('Page not found, check the name...') and then returns the control to the program.
But I dont' know if I opened (or not) the page...

It will be usefull a return value (true or false) to check the situation.
In this case - IF result=0 go to page 404.html (that exists!)

Thanks!

EDIT:

Nevermind!!! I think I've resolved with HtmlViewStatus
